273 to 383 Formula S Barracuda

The Formula S 4 speed would have a Commando 273. Very cool cars and your headaches will melt away. Any 273 runs well, just like any SBM, just add a cam and valve springs.
I am kind of regretting not taking the time to do the research before I rebuilt the 383. I still may try to get the 273 rebuilt but I have seen that rebuild kits are hard to get without having them custom built. I'm not looking for high Hp just a good cruiser that the wife and I can drive.
